latch 11 is adapted to engage to secure the window in closed position.

To provide it suitable stop for the win dow when it is unlzuched and theupper portion swings away from the hitch strike, the metal flange of theupper portion of the frame is upset on its front face to form the flop12, against which the outer face of the sash abuts and holds the s: shin horizontal position, as clearly shown in lligs. and l. The portion ofthe metal upset, us described, is a portion of a flange 14lwhich on theexterior face extends downto this point. A similar flange 15 is formedon the inner face of the casing, which also acts as :1 stop, end a.tight fit for the sush when it is in the closed position. Secured tothese vertical flanges are a plurality 01'? clips 16, those of the uppersection not with the upturned flop 12 to form an el'lioient support forthe screen frame 17 inclosing the screen 18. The lower edge of the frame1'7 terminating close to the sash 7 and the glass contained therein, sothat the opening therebctwccn is not of sutlicient height to permit theentrance of insects.

The clips 16.011. the inner flange 15 together with flanges 19 on thelower section 20 of the casing, form efficient supporting clips forthe-inner screen frame 21, which is also provided with a screen 22, theparts being so arranged that the upper edge of the screen 21 abutsagainst the inner face of the swinging; portion of the sash when theletter is in its horizontal or open position.

W hen it is not desired to have the screen in the window, the some maybe readily re moved by slipping the vertical part of the frame, theouter one with the window in open position, and the inner, necessarilywhen the window is closed.

The screen frames 1'? and 21 are preferably formed of metal, as are allof the other parts, constituting a fire proof structure, and arepreferably built of narrow int channeled metal, within which the edgesof the wire screen are efficiently clmnped.

hat I claim is:

1. A window screen construction comprising; a window casing having s deand end walls, the side walls thereof hei provided with inclined slotsand oppositely disposed flanges adopted to engage e window sashpivotnlly mounted in the slotsin the side of said casing, o. pluralityof vertically dis-- the upper flanges of said vertically andhorizontally isnid casing on its inner flanges on the inner posedclips'secured to said casing adjacent I vWindow casing, said flangeshaving an upset end adapted to form a support for a screen, a pluralityof disposed clips secured to the edges of the lower section of face, andscreened frames oppositely disposed on said casing,

the upper/of said screens being supported upon said upturned flanges andsecured by said vertically-disposed clips, and the lower of said screensbeing secured by the vertically and horizontally disposed clips on theface of the casing, whereby said Window-sash may be pivotally swungscreened.

2. A screen frame construction for ventilating WlIldOWS, frame adaptedto opening a Window pivotally mounted in said-frame to form a closurefor the opening 5 and the exposed area efficiently comprising. astationary be secured in a Window a screen mounted on the outer upperhalf of said frame end disposed in parallel relation therewith, a secondscreen mounted on the inner face of the lower half of said frame anddisposed in parallel relation therewith, the upper edge or" the lowerscreen and the lower edge or the 11 per screen each terminating at oneside of: the pivotal points of said window, the space between the twosaid screen edges approximately corresponding to the thickness of thepivoted Window, whereby when the window is swung from a vertical to ahorizontal position the space between the adjacent edges of said screenswill be substantially closed.

In Witness that Q" the foregoing l have hereunto subsc my name this12th.
